Application fil ed November 2, 1910. Serial No. 590,401.

To all whom 'it concern Be itknown that we, WILLIAM HENDER- SON and ALEXANDER M. HENDERSON, of

Aurora, in the county of Kane and in the State of Illinois, have invented a certain new and useful Improvement in Capsules, and do hereby declare that the following is a full,'clear, and exact description thereof.

This invention relates to breeding appliances, and more particularly to such as are used in the impregnation of mares.

The object ofv the invention is to provide a device for the purpose stated which will possess the desirable qualities of great efficiency, simplicity, capability of'use even by a layman, and security against infection.

g of the mare, and to this end the invention consists in the impregnating capsule con- 'structed substantially as hereinafter specified and claimed.

Referring to the nnexed drawings:

Figure 1 is aperspective view of a capsule embodying the invention, the several parts I being shown as separated; Fig. 2 is a longitudinal sect-ion thereof, the parts being assembled.

As preferably constructed, the device is composed of three members made of gelatin. One is the capsule proper, or body, 10 of tubular form, with one end closed and the other open, but with an inwardly turned,

tapering or conical flange or rim 11, that is joined at its larger end to the end of the tube by a convexly rounded portion. Each of the other members'is a cap, one cap 12 having a taperingv or conical form with a short cylindrical open endto slip over the closed end of the body -10-;'and the other cap 13 being of blunt, cylindrical-form, and adapted to slip over the open end of the capsule body 10 to form a closure.

The manner-of use of thecapsule is as follows :The mare is served by a stallion.- If she is not a sure breeder, an attendant places arcaps'ule without. the closure cap 13,

m the palm of hisha nd, and then'inserts it V the vagina and scoops up therefrom some pointed cap, which dilates of the semen,

close the opening by being placed therein. and access of air to the interior of the capsule be prevented, which is desirable when transferring semen from one mare to an other, for this is one of the uses to which the invention may be put, so that the service of one mare may be used where more than one mare is to be bred,- it being possible for five or six mares to'be thus bred. The capsule being charged with semen by the scooping operation described, it is inserted int-o the uterus of-the mare, andleft there, where it willdissolve and free the semen. Its insertion is rendered easy by the tapering the neck of the uterus .gradually and easily, and its presence in the uterus causes the latterto contract and so prevent the escape of the semen.

A capsule, of course, is used but once, and its superiorityin this regard over the use of a syringe that is repeatedly used will be apparent in that danger of infection is avoided, antl'nobreeding place for bacteria is aflorded. The opening-closing cap is used only when the semen is to be sent long distances, as by mail or express. If need be, it could besent a thousand miles.

By means of this invention mares regarded as sterile may be gotten in foal.

VVhat'we claim as our invention, is

1. A soluble capsule comprising'a hollow body that has an opening with an inwardly turned flange.

2. A 50111 le capsule comprising 'avhollow which readily enters theopen 7 end of the capsulefbody and is retained or injury body with an exterior that is rounded and which is elongated and has at one end an opening with an inwardly turned flange.

I 3. A soluble capsule comprising a hollow removable cap for said end, and a tapering 13 body with an exterior that is rounded. and extension at the other end. which is elongated, and has at one end an In testimony that we claim the foregoing opening with an inwardly turned flange, we have hereunto set our hands. p

and a tapering extension at the other. end. WILLIAM HENDERSON.

4. A soluble capsule comprising a hollow 1 ALEXANDER M. HENDERSON. body with an exterior that is rounded and Witnesses: which is elongated and has atone end an 7 PAUL W. HEALY, opening with an inwardly turned flange, a W. H. HEALY.
